Clonazepam is a medicine used to treat seizures. Anti-epileptic drugs, benzodiazepines such as clonazepam in particular, should be reduced in dose slowly and gradually when discontinuing the drug to mitigate withdrawal effects.

Point of Care Testing ConsiderationsSome point-of-care testing (POCT) devices may result in a false positive for benzodiazepines in patients who are taking certain medications.6,11-17 Cross reactivity can occur with this type of testing among drugs with similar chemical structures.11 Non-benzodiazepine prescription, illicit, or over-the-counter drugs would not cause a false positive for benzodiazepines or benzodiazepine metabolites on Aegis definitive testing.
